I guess that's kind of the point. You don't have to choose to be that kind of grown up.

There is work that is unpleasant but needs to be done (chasing raceconditions, memory leaks, etc.) - and there is grind, that kills all your love for the project. If it is the latter, I really do recommend to make a break and do something else. I tried both and grinding did not work out, but coming back fresh did and I usually immmediately spotted the problem, I otherwise would have wasted lots of energy on it.

Yes, but it's okay to refuse to grind. Sometimes the juice is not worth the squeeze, and it's equally grown up to give up.

As a grown up I can choose to enjoy a project until I stop enjoying it.

Does every project actually need to be brought to its conclusion? No. Is it nice to take pride in completed projects? Yes. Do the projects I do bring me additional knowledge? Yes, usually.

I think that the ability to complete a project is a desirable skill. I think the desire to take a project to completion is worthy, otherwise why start it? Still, priorities change right along with interests. Much like saying "No" is considered a skill, knowing when to finish, and when to throw in the towel, are both equally valuable skills.

When I signed my daughter up for soccer this summer I had to willingly drop a personal and extremely fun side project because I've committed an extra 4+ hours/week to her development. Am I not a grown up for making this decision?

> Am I not a grown up for making this decision?

No, of course this is not the case. You made a decision based on priorities.

The headline of the article:

> Finish your projects > Don’t let fear, or that last 10%, hold you back.

... and reading the article, it seems targeted at people who want to finish their projects, but are struggling with the reality of actually doing so.

GP seems to be talking about the same sort of thing --- giving up because the going got grindy.

It's of course fine to just screw around in your free time if the goal is to screw around in the first place. It's also fine to realize that some goal (project, etc.) you set no longer aligns with your priorities.

I feel like there are two groups of people here talking about different things but thinking they're the same.

The difference is perspective. You're right that grind is unavoidable, but it requires a big-picture perspective that the work is still valuable and therefore worth completing. If the wider circumstances have changed, then grinding because success demands grinding belies the fact that success will no longer be achieved through grinding. The key, in the beginning, is to attempt to reduce the amount of grinding that will be necessary by reducing scope as much as possible for what is needed to ship; the less grinding you need, the more likely you are to ship, and the more likely you are to continue to ship in the future.

I apply that mentality to my job. If I’m just goofing around at home I don’t “have to” do anything.

That's absolutely true. Alternate perspective, though --- might it be that "goofing around" was the goal here, and therefore the goal was accomplished?
